Question
Give reason : The genetic engineering is alternatively called recombinant DNA technology or gene cloning.
✓
Answer
- Genetic engineering involves the manipulation of genetic material in a directed, predetermined, in vitro way to develop a desired end product.
- It manipulates the genes for improvement of living organisms,
- It involves repairing of the defective genes, replacing of defective genes by healthy genes or normal genes and artificially synthesizing of a totally new gene.
- Genetic engineering also involves transfer of a new gene, transfer of genes to a new location or into a new organism, gene cloning, combining of genes from two organisms.
- This results in alteration of the genotype and desired products can be developed.
- Therefore, the genetic engineering is alternatively called recombinant DNA technology or gene cloning.
